#4 The Skyblues were guilty of missing too many chances

Celta Vigo could've pulled off another major shocker like they have in the previous two seasons when they hit Barcelona for a four. The only difference here was in the poor finishing, unlike in those two occasions when they fired at all cylinders.
Chance were aplenty again, as Daniel Wass, Iago Aspas and Maxi Gomez were among the chief creators on the night, but were left undone by some subpar finishing. Those two strikers especially had enough opportunities to bury the game long before the final whistle.
Ter Stegan deserves credit for his share of blocks and interventions, but there were moments where even he couldn't have done anything had Celta been a little more precise and unerring.
Barcelona were really let off the hook here.
